Windows Defender is not enough alone to protect against viruses
Windows Defender Antivirus is pre-installed in Windows 10 and provides good protection against malicious software and code. However, PC Magazine advises desktop and laptop owners not to rely solely on protection because it has been "well" tested.
Although Microsoft did not look bad on the test, it was the worst of the 11 test programs paid.
One of the advantages of the Devender program is the launch of a few false alarms, and a protected folder since the release of Windows Update 10 to eliminate encryption. But it is notorious for its strong need for operating system resources and its limited ability to identify viruses and malicious code.
Windows Defender is automatically activated in Windows 8 and Windows 10, but it disables itself when installing third-party antivirus software.
The results of the German magazine were led by BitDefender Total Security, MultiDevices 2018, Kaspersky Total Security and Avast Premier, and GData Total Security was the best program to achieve the cost-efficiency equation.
Anti-virus software offers many add-ons, with some programs providing secure webcams, or trying to protect users from web-based tracking by advertising and advertising companies or website operators.
Some anti-virus software offers special offers for VPN, spam or e-mail monitoring, and some paid antivirus tools offer a special protected browser for online banking.
Free editions of paid anti-virus programs often provide basic protection, but they include a limited range of jobs and occasionally show ads.
